To all whom t may concern Y Be it known that I, Jiosnri-r GALLEAZZI, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Educational and Amusement Devices, of which the following vis a specification.

This invention relates to improvements in educational and amusement devices of the type embodied in my U. S. Letters Patent No. 1,386,248, issued August 2, 1921.

The primary object of the invention is to provide an educational and amusement device by means of which a great many different subjects of instruction or teaching may be effectively and impressively brought to the attention of the persons receiving the instruction. This is accomplished through the instrumentality of mechanically operated means which may be put into operation by turning a small crank handle at the side of the machine or may be power o-perated, the mechanism of the machine operating so that different indicia relating to the several subjects will be presented to view each time the machine is operated, it being impossible to determine in advance, what particular indicia will be presented to view.

Another object is to provide a machine or device of the character described with which arithmetic, history, geography, reading and spe-lling may be taught, the machine operating in such manner as to hold the interest of the pupils and prove amusing with the result that the instruction will be more impressive.

A. further object is to provide a machine or device of the character described with which a thorough course of instruction, in a plurality of subjects may be easily given, the machine being comparatively small, compact and relatively inexpensive, commensurate with effectiveness and utility.

A further object is to provide novel means y for regulating the display of indicia relating to certain subjects.

This invention possesses other advnntages and features some of which, with the foregoing will be set forth at length in the fola lowing description where l sha-ll outline in full that form of the invention which l have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings l have shown one form of the construction ofv my Specification of Letters Patent.

Figure 8 is a fragmentary vertical sectional view taken at right angles to Figs. 6 and 7 and. showingl in particular the automatic disc stopping means, front elevation.

Figure 9 is a fragmentary front elevation of ythe device with the cover and front wall removed and showing the walls of the casing in section and the mechanism in elevation.

in carrying out the invention l employ a suitable casing or housing, capable of being mounted upon a stand or table, and

mount within the housing mechanism `for presenting to view through openings in one wall of the housing, a variety of indicia relating to varioussubjects of instruction, such as history, arithmetic, and geography, the mechanism being` operable by the turning of the crank handle on the outside of the housing and may be power operated, if desired. y

Referring particularly to the embodiment of the invention illustrated in the accompanying drawings, there is provided a casing or housing 10, which is made up of a bottom wall 11, rear wall 12, end `walls 12, and a comparatively low front wall 13. A

lcombined cover and front wall 14 is hinged as at 15 at the upper' end of the rear wall and rests upon the upper edge ofthe front wall 13, said cover being provided with a series of slots or openings ysuch yas will be later more fully described, for the purpose ,of permitting the indicia on the displaying mechanism to be viewed.

The displaying means for presenting the :indicia of the different subjects of instruction are in the form of discs,.drums and rollers, the discs and drums being loosely mounted upon revolvable shafts in such manner that, when `the shafts are rotated said discs and drums will, by frictional engagement with 'said shafts, be correspondingly rotated, but when held, will permit said shafts to rotate independent thereof. Extending transversely across the upper side ofthe housing or casing a revolvable shaft 16, having loosely mounted thereon adjacent to one another, a plurality of comparatively thin circular discs 17. yBetween the discs are washers 18, which provide for s acing of the discs relative to one another.

he openings 19 through the center of the discs', which openings receive the shaft 16, areof such size that when the shaft is rotatedthe discs will be correspondingly moved, but so that certain of the discs will have a greater degree of movement or rotation .than the others. This relative degree of rotation being provided for, not only by the loose frictional engagement with the shaft, but through the instrumentality of the washers 18, opposite faces of which engage the opposed faces of the discs. Each of the discs is provided upon its periphery and transversely, with indicia in the form of numbers designated 20, said numbers being spaced apart a predetermined distance. Between the numbers are painted, printed or otherwise caused to appear, on the discs, a plurality of characters 2 1, such as pid tures of animals or fruit.l There are preferably provided several discs, so that figures from zero to a million in various combinations and units may be presented to view as desired. The discs are mounted adjacent g to one end of the housing `and close to the front wall or cover 141. Formed through said front wall 14 are a plurality of small. square openings 22 4in a :horizontal row, each opening Vbeing spaced 'from the other and arranged to be opposite the periphery of one of the discs. Above the row of openings,jthe designation Numbers may be printed, as shown at 2,3.

Loosely mounted upon the shaft 16 are circular drums 241, 25 and 26 having the same diameter as Vthe discs 17. 'Washers 27 loosely surround the shaft 16 and space the drum 24 from the adjacentdisc 17 and from the drum 25. The disc 23, corresponds in size to the disc 17 and is loosely mounted upon the shaft 16 between the drums and y26, said disc being spaced from the said drums by vloose washers 29. The remaining portion of the shaft 16 has a plurality of discs 30, 31, 32, 33, 3a, and 35, loosely mounted thereon, said discs being of various thickness, dependingupon the indicia to be placed or carried thereon and being spaced from one another by loose,y

washers 36. All of the'discs and drums are of the same diameter so as to bear the same relation at their peripheries to the front wall 14. The drum 24 will have printed thereon, the names of famous persons, for j sent these subjects and extend transversely on the drum. The 'front wall is provided with slots 11 and 12 to provide for the displaying` of the designations 39 and 40. i The disc 28 may contain the designations 43, indicating the days of the'month and a small longitudinal opening la is provided inthe front wall to permit of the displaying Vof such designations. The drum 26 may have designations 45 thereon, representing .Y the,

days .of the week, and the opening 16'is provided in the front wall opposite this drum. The discs 30,' 31, 32, 33, 351 and may respectively bear designations L17, 18, y41-9, 5U, 51 and 52, representing the'hours ofthe day, the time, M P-M.) the cardinal and inter-cardinal points of the compass, the notes of music, the different phases of the moon and the `letters ofthe alphabet. vThe front wall '14 is provided with a series of spaced openings 53' arranged opposite the discs 36 to 35 inclusive. The openings and slots in the front wall la are in the same horizontal plane so that the indicia will be presented in a row extending entirely across the front of the housing` and may be read from left to right or otherwise, as desired. It will be seen that any number of discs and drums may be employed "for presenting or displaying indicia relatingto different subjects, and I wish it understood ythat l do not limit myself to the number of discs and drums herein shown or to the number of subjects of instruction.

rPhe mechanism hereinabove described takes up the entire upper part of the casings or housings from end to end thereof and similar mechanism designated 511 is likewise extended across the lower `side of the housing. rllhe mechanism 54 comprises a' plurality of drums 55 of circular form, loosel mounted upon a horizontal shaft 56, whic latter is rotatably mounted in suitable beardrums 55 are spaced slightly from the discs and drums and above'them have designations or indicia 58 transversely on the peripheries thereof, said indicia representing the countries ofthe different continents such as Europe, Asia, Africa and the American Continent, which is preferably divided so that one drum refers to South America and the other to North America, the United States and Canada. Any designations rela tive to the subject of geography may be borne on these drums as desired. A plurality of slots 59 are formed through the front wall 14, opposite ythe drums 55, whereby the indicia thereon may be readily presented to view.

Mounted forwardly of and between the kupper and lower mechanism is a circular roller 60 having its trunnions 61 journalled in the end walls of the Vcasing or housing. This roller is equal in length to the rows of drums and discs and will have on the periphery thereof spaced-rows of indicia 62 representing the names kof famous men, islands etc. A plurality of slots 63 are formed in the front wall so as to provide for the presentation of these names. On the front wall extending transversely across the outer face thereof, there may be provided other designationsor indicia representing linear and metric systems, 'and weights and measures, as shown by the designations of characters 64, 65, 66 and 67. Anyother table or scale of measurements or like data may be printed or otherwise caused to appear on the front of the housing or casing. Between these characters or indicia 64, 65, 66 and 67, which characters are spaced in horizontal rows, are rovided longitudinal slots 68 and 69. lV ounted within the housing is suitable mechanism to provide for the movement of kpointing or designating members 7 0 and 71 along the slot, during the operation of the machine, the said pointers or designating members when opposite the designations 64, 65, 66 and 67 indicate that such designations are to be read by the pupils. v

The means for operating the shafts 16 and 50 also the roller 60 comprises a crank handle 72 upon a shaft-78, which shaft is journalled in one end of the wall of the housing and projects outwardly therefrom to provide for the attachment of the crank handle. A pinion 7-4 is 'fixed to this shaft and meshes with a large gear 75 fixed to the shaft 16 and also meshes with a large gear 76 fixed to the shaft 56. This provides for the rotan tion of the shafts 16 and 56 and the various discs and drums mounted thereon. The shaft 73 also carries a pinion 77 which meshes with an idler gear 78 mounted on the shaft 78 supported by the end wall. The

Avided for. l are mounted upon rods 79 rotatably sup` idler gear 78 meshes'with a pinion 79 fixed to the adjacent trunnion 6l'of the roller 60 and in this way rotation of the roller is pro- The pointer members 71 and 72 ported by the end walls of the casing. Certain ends of these rods are lifted up and down during the 'operation of the machine, by mechanism which will be later more fully described, whereby the pointer members will gravitate on said rods.- To prevent the sticking of these members and insure the movement of said pointer members, the rods are rotated. Small gears 8O are fixed to certain ends of the rods and mesh with idler gears 81 supported by the adjacent end wall, and the idler gear meshes with the pinion 78.

To provide for automatically stopping the discsand drums so as to bring the designations thereon opposite the openings and slots in the front wall or cover, suitable mechanism for engaging portions of said drums and discs is provided and is arranged to be operated from the gear 76. This mechanism comprises an eccentric track member 82 mounted upon one side of the gear 76. A shoe 83 is arranged to engage in said track member 82 and is supported upon one end of a rod 84, which rod is fixed, as at 85, at its other end to a rotatable horizontal shaft 86 extending transversely across the casing adjacent to the back wall thereof. The shaft 86 is suitably rotatably supported as at 87, in the end walls of the casing. Depending from the shaft 86 is a curved arm 88, the upper end ofwhich is fixed to said shaft. The lower end of the arm is recessed as at 89 and receives an upstanding lug 90, carried upon a bar 91, which bar .is slidable for-A wardly and rearwardly upon suitable supporting means 92. The bar 91 extends .horizontally and rearwardly of the set of drums 55 adjacent the lower sides of said drums. A plurality of stop pins 98 are carried by the bar 91 and project horizontally and forwardly therefrom. The drums 55 are provided cn the side faces thereof adjacent their peripheries with lugs 94, with which the pins 93 engage when said pins are moved forwardly. lVhen' this takes place the drums 55 are held against rotation and the shaf 56 rotates freely, relative to said drums. The eccentric track 82, lugs 94 also the elements 84, 88, 91 and 93 are so arranged that when the crank handle 72 is rotated the drums 55 will be rotated several times before the stop pins 93 move into position to engage the lugs 94 and furthermore, so that when this engagement of the stop pins and lugs takes place,the indicia on the periphery of the drums will be presented opposite the slots or openings 59.

Fixed as at 95 to the arm 88, at a point in` termediate of the ends of said arm and projecting' outwardly at right angles thereto, is

and forward onthe support 101.

l elink 96y piroted atf97 to an upright arm- 98. l T he v lower-mend of the arm 9S is pivoted as at '99 to the lower Wall of thehousing. The arm 98 .extends upwardly to arpoint adjacent but spaced rearwardlyfrom the dises 17. A

horizontal bar or rod 100 is slidablefon .wardly and rearwardly Vupon a support 101 therefor, vWhich support 1s secured to the bottom'andfrear walls .of the housing.

vtend-ing rearwardly -fro'mthe bar 100 is, an eye `orstaple 102 whieh engages in a bifureation103,-f.ormed in the upper end of the arm 98. Thus when the arm 98isroeled on i .andl adjaeenttheir peripheries, with lugs 106 .is-paced apart so that they may encounter the pins 104. Whenthe pins /1 engage the lugs 1.06 the dises and drums are brought to rest Withthe designations .opposite the openings end-slots 1n thefront Wall.

rlhere is provided signaling means for in- -fjlicating to the operator when the operation of theeranlr handle must be stopped, which me-ans is preferably in the form of a bell 'thatis .caused to ring at suoh time when the drums and dises have ythe indicia thereon alined so as to be presented at the vopenings and slots :in the front Wall .of the housing. rIhis bell 107 is mounted upon .one end Wall ofthe honsingand operated by a striker 109, `one yend of 'which is disposed to be engaged by the lug 110 provided on the gear 75. The lug will engage the striker once during eaoh rotation of the gear and during eaoh rota* tio-nef vthe gearthe drums and dises will rotate several times. v

To provide for the vertical ymovement of the rods 79', at one end of each ofthe rods the pointer members to slide, there isV provideda gear 112 which is lixedto the shaft and 122 are mounted. The rocker arms are f pivioted intermediate their ends as at 123 to the adjacent end Wall. The other .ends of the rocker armsare slotted or bifuroated as at 1211, and receive pins 125 of two slide members 126 and 127 both of which slide eration. so as to Cause said rods to be inclined and members are movable-.in .a vertiealguide 1.1.2.8,

Each `of the .stop memberslBO extends through an opening 13e in `the front Wall 111 and is adapted to engage rwiththe lugs 1,06 .on oneof the discs 17 Each stop member .sprovided with a lug which is adapted, when the member is Withdrawn or pulled outwardly, to engage; on the outeredge .of the guide nie-ans therefor, so as .to hold said member in outwardly extending. position, the guide nie-ans being slotted on one sideto allen7 for the inward projection ofsaid stop `member 'llo projecta stop member inWardlyAV-it .is turned, so as to bring .the llugl in line With the open side ofthe guide means, and is ,then pushed inwardly so thatl .the inner' ends thereof will engage with one .of .the lugs 106. lt will thus beseen that it is possibletoV hold as many of the dises yas desired against opf Operation;

,ln use, the .device ormaohine is Aplaoed .i

upon a stand or'support andthe operator .by turning the handle 7 2 puts the maohineinto operation. Vhen the handle 72 yis turned vthe shaft 7 3 is rota-ted and thus rotates the pinions 711 and 77.. Rotation of the-pinion ,711 transmits rotary movement to the gears 7 5 and 76, which gears' are fixed-respectively to the shafts 156 and 56. By reason of frio- .;tional sengagement of the discs and drums on the respective shafts, with said shafts, the said discs anddrums are rotated. Inasmuoh as the degree of friotional engagement between these .shafts lthe Various drums and discs Will vary, thedegree of rotation ofsaid dises and drums Will likewise vary during the rotation of the shaft. The-,mechanism is so geared that the .dises 'and drums `will rojected' into position to engage the lugs 106 y on the discs and drums mounted on the upper shaft. It will thus be seen that the pins 93 are simultaneously moved'to engage the lugs 94 and upon such engagement all lof the drums on the shaft 56 will be brought to rest with certain indicia thereon opposite the slots 59. At substantially ythe same time the lugs 1,06 engage the pins 104 and the discs and drums on the upper shaft are brought to restwith certain indicia thereon registering with the various openings and slots for re` vealing such indicia. Immediately when the vpins 104 and 93 move into position for engagement with the lugs 95 and 106, the gearv 75, will have been rotated through one complete revolution and the lug 110 thereon engages the striker 109 so as to ring the bell.`

This is the signal for the operator to cease turning the crank handle. When the pins 104'and 93 are extended into position to en gage the several lugs or the discs and drums, by reason of the fact that certain of the discs and drums will have stop lugs thereon spaced apart distances at variance with the spacingvof the lugs on other discs, cert-ain of these lugs will engage the stopl pins -be-v fore the lugs on other of the discs and drums move into. such engagement. Thus, when the bell rings the several discs and drums have all been moved into position to aline the indicia of the several discs and drums with one another, and the lugs of the several discs and drumsare engagedwith the stopl pins whereby the indicia will be presented in even rows across thefront of the machine. The bell therefore is a signal to indicate that the combination of indicia is formed for presentation at the openings and slots and the operation must be stopped. Tf the shaft is turned through the instrumentality of the crank handle,y after the ringing of the bell or signal, the gears operating the device for moving the pins 93 will be operated so that the, pins might be withdrawn, this, however,

being dependent upon the amount of turningy of theshaft after ringing of the bell. However, if the pins 93 are withdrawn, the combination indicia which has previously 'been alined for vpresentation'will be destroyed and moved outof alinement. For this reason the bellis a signal to prevent rotation ofthe shaft past a point which projects the moved out of stopping position. The bell signal makes it unnecessary 4for the operator to watch the presentation of the indicia at the ktime of operating the machine andin this way makes it unnecessary to lassume stooping position or stand in front of the machine in order to view the indicia. Dur-l ing the rotation of the shafts 16 and 56, the roller 60 is rotated, by reason of the gears 7 7, 7 8 and 79. These gears are so arranged that when 'the discs and drums are brought to rest the roller willcease to rotate and bring the indicia thereon into registration with the slots 63. As the roller 60 rotates the gears 81 and 80 meshing with the gear 79 provide for the rotation of the rods 7 9. Simultaneously with the rotation of the rods 79', said rods are movedl at certain ends thereof so that said rods are oppositely inclined. This takes place as the shoe l116 moves laterally in the eccentric track 11,5 and the arm 117 oscillates, the gear 112 be-` ing driven through gea-rs 113l and 114. 'As l the arm 117 oscilates the rockerl arms 121 and 122 are rocked so as to move the slide means 126 and 127 downwardly and up wardly respectively. This movement of the slide members to which slide members, the rods 79 are attached, causes said rods to be inclined in opposite directions. By reason of the inclination and rotation of said rods, the pointer members 70 and 71 will slide longitudinally and come to rest adia cent of certain of the designations 64, 65, 66, andv4 67. The slide members indicate the point to which thepupil must read the indicia, reading from left to right.` Thus, if the pointer stop halfway, the pupil would read from left to right up to the point at which the pointer stops. I

Assuming that all of the stop members 139 are in out-of-theway or withdrawn position, the discs 17 will each present a vnumber` opposite the openings in the front wall ycharacters 21 in registration with the open- 11b ings 22, which characters may be pictures ofanimals or of fruit or the like as previously described. It will thus be seen that numbers in unitsvof tens, hundreds etc., up to one mil--v lion may y nipulating the stopmembers 130.

v Summing up the presentation of data prof vided by oneoperation of the machine, it is seen that a variety of subjects of instruction will be presentedin a unique and impressive manner. Reading from the left upper end of the machine, there will be a horizontal rom/numbers or other characters, then the name of one `of the Presidents of the United States, the season ofthe year, the day of thel bepresented, as desired, by ma- 120l v ing the indicia.
